- open end warm up test on a low carbon steel fastener
- box end torque test to rounding using soft coupling nuts, wrenches extended to equal length
- open end failure load test using a half inch Allen key until the jaws stretch, bend, or slip
- box end failure load test using a hex Allen key until the wrench bends or breaks
- back and forth slop measurement on both the open and box ends using a dial indicator
